Lane E round 5 (E3): fal Hunyuan glass_case + bus_shelter + magazine_rack (~$0.64)

The 2 R3 TRELLIS glass rejects + optional magazine-rack, generated on fal.ai
Hunyuan3D v2 (John-authorized, $22 balance). pipeline/gen_props_fal.py drives the
fal operator using the FAL_KEY from MODELBEAST settings (never hardcoded). Frosted/
opaque flux_local concepts gave the reconstructor a surface (clear glass defeated
TRELLIS). glass-case 1 att, bus-shelter 2 att (opaque back wall), magazine-rack 1 att
= ~$0.64 total, guardrail held. All baked to <=8k via bake_lowpoly.py (switched to
EMIT albedo bake — Hunyuan materials bake near-black under DIFFUSE). Verified loading
in vendored GLTFLoader, published, validate --depot 0 err. Manifest 17 fittings + 9
furniture; aliases wire glass_case/glass_cabinets/magazine_rack/fridge/listening_corner.
Costs logged in AUDIT R5. Last 2 primitive-only fittings retired.
